IMMUNOLOGY

Detailed explanation-1: -Plasma cells are differentiated B-lymphocyte white blood cells capable of secreting immunoglobulin or antibodies. These cells play a significant role in the adaptive immune response, namely, being the main cells responsible for humoral immunity.

Detailed explanation-2: -Synthesized exclusively by B cells, antibodies are produced in billions of forms, each with a different amino acid sequence and a different antigen-binding site.

Detailed explanation-3: -B lymphocytes, also called B cells, create a type of protein called an antibody. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection.

Detailed explanation-4: -Plasma cells, also called plasma B cells or effector B cells, are white blood cells that originate in the lymphoid organs as B lymphocytes and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens.

Detailed explanation-5: -Plasma cells develop from B cells that have been activated. A plasma cell is a type of white blood cell. Also called plasmacyte.
